Definition:
YIELD is a measure of the extent of a reaction, generally measured by comparing the amount of product against the amount of product that is possible. Yield is generally expressed as a percentage.

Usually, percent yield < 100% (actual yield < theoretical yield)

Reasons for this can include:

incomplete or competing reactions

loss of sample during recovery

% Yield = actual yield/ theoretical yield  x  100

If a reaction is 85% efficient, it means it yields only 85 g actual product out of a theoretical maximum of 100g.

1. Calculate the number of moles of NaOH that are needed to react with 500g of H2SO4 according to the following equation:
H2SO4 + 2NaOH —> Na2SO4+ 2H2O
ANS: 10.19 mol

2. Calculate the mass of NH3 that can be produced from the reaction of 125 g of NCl3 according to the following equation:
NCl3+ 3H2O —> NH3+3HOCl
ANS: 17.7 g

3. Determine the mass of CO2 that can be produced from the reaction of C3H8 with 75.0 g of O2 according to the following equation:
C3H8 + 5 O2 —> 3 CO2 + 4 H2O

4. How many grams of SO2 are produced when 152 g of CS2 react with 48.0 g of O2 according to the following equation:
CS2 + 3O2 —> CO2+ 2SO2
